TYPO3 Core

Can you provide a repository link to the source code of your extension? Otherwise it's getting difficult to guess your configuration and things you maybe are doing there. Thx.

And please provide a short step-by-step guide on how to reproduce this behavior in a particular scenario (with your extension probably).

The "Element ... does not exist" thingy seems to be related to #67676 (deleted child elements in a workspace).

Problem 1 is a general problem. It occurs always (not only in the workspace mode). When I select a file with this FlexForm

        <templateFile>
            <TCEforms>
                <label>Template file</label>
                <config>
                    <type>input</type>
                    <default></default>
                    <wizards type="array">
                        <_PADDING>2</_PADDING>
                        <link type="array">
                            <type>popup</type>
                            <title>Link</title>
                            <icon>link_popup.gif</icon>
                            <script>browse_links.php?mode=wizard&amp;act=file</script>
                            <params type="array">
                                <blindLinkOptions>page,url,mail,spec</blindLinkOptions>
                                <allowedExtensions>htm,html,tmpl,tpl</allowedExtensions>
                            </params>
                            <JSopenParams>height=300,width=500,status=0,menubar=0,scrollbars=1</JSopenParams>
                        </link>
                    </wizards>
                </config>
            </TCEforms>
        </templateFile>

Problem 2: when I am in the Draft workspace and select a uploaded file with this code:

$TCA['tx_myquizpoll_question'] = array (
    'ctrl' => $TCA['tx_myquizpoll_question']['ctrl'],
    'interface' => array (

1: The destination (/var/www/html/server/uploads/tx_myquizpoll) or the source file (/var/www/html/server/uploads/tx_myquizpoll/5011) does not exist. (tx_myquizpoll_question:505:image)

then only "file:3453" will be stored in the FlexForm data.
templateFile should contain the path to the file - like in TYPO3 4.x - and not only "file:3453".
Is that a bug or do I need to chance the FlexForms?

That's the effect of the file abstraction layer (FAL). Only references to a file entity are stored, not the full path anymore.
If you put "file:1234" to ResourceFactory::retrieveFileOrFolderObject() you get the accordant file entity.
Thus, that's not a bug, but something that needs to be changed in the processing logic of your extension.
